To all whom it may concern Be it known that I, GEORGE V7. DAVIS, acitizen of the United States, residing at Gibson City, in the county ofFord, State of Illinois, have invented certain new andusefulImprovements in Corn Feeding and Debutting Machines; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit apper tains to make and use the same.

This invention relates to new and useful improvements in corn machines,and particularly to machines for cutting the butts and heads of ears ofcorn, preparatory to husking or otherwise treating the ears.

One object of the invention is to provide a machine wherein the ears arefed in proper position to the debutter, and means for moving the earsfirst into position for cutting one end, and then into position to cutoff the other end.

Another object of the invention is to provide a feeding mechanism whichwill turn the ears so that they will be delivered longitudinally to thehopper of the debutting machine.

Other objects and advantages will be apparent from the followingdescription when taken in connection with the accompanying drawings.

In the drawings:

Figure 1 is a side elevation of a debutting machine, and its feeder.

Figure 2 is a top plan view of the same.

Figure 3 is a vertical transverse sectional view on the line 33 ofFigure 2.

Figure t is an enlarged elevation ofone set of rotary cutting disks.

Figure 5 is a vertical sectional view line 5-5 of Figure 4. v

Figure 6 is a vertical longitudinal central sectional view through thefeeding mechanism, on the line 6 6 of Figure 2.

Figure 7 is-a transverse sectional view on the line 7--7 of Figure 6.

Referring particularly to the accompanying drawings 10, represents atable top which is supported on the legs 11. and which legs are properlybraced at 12. j The legs 11 are preferably formed from angle metal. Theintermediate legs 11 extend above the table on the top, as shown at 13,and carried by these extensions, with-its ends secured thereto forvertical adjustment as indicated at it, is the transverse member 14;;The upper ends of:

the end legs 11 are formed with the bearings 15, for rotatablysupporting the ends of the shafts 16 and 17, sprocket wheels 18 beingfixed 0n the shafts for supporting the endless belt 19. Secured t0 thebelt, and extending transversely thereof, are the flights 20, betweenwhich the individual ears of corn are adapted to lie, and be carried bythe belt to devices for severing the heads and butts, as will be moreparticularly described later herein.

Secured to the side edges of the table top, at points intermediate theends and intermediate legs 11. and 11, and extending verticallytherefrom, are the supports Adjustably connected, at 21 to the ends ofthe supports 21, and extending transversely over the conveyor belt '19,are the bars 22. Mounted on each of these bars 22, and on the member 14,are bearing brackets 23, which rotatably support the ends of the shafts24 and 25, which extend longitudinally of the belt and table top. Fixedon the shafts 2 1- and 25, respectively, are the cylindrical rotatablebrushes 26 and 27. The inner ends of the shafts 24 and 25 are disposedadjacent each other, and each has a gear 28 thereon, meshing with thegear of the other shaft. By this arrangement the brushes will be rotatedin opposite directions, with relation to each other. The brushes aremounted in such positions, on the supports, that their bristles extenddown into the spaces between the flights 20, for moving the earstransversely of the belt, and longitudinally of the flights, toward theedge of the belt. By means of the adjustments shown at 14: and 21 thebrushes are capable of being raised and lowered. On each longitudinaledge of the table top there is mounted a vertical side wall 29, andformed through one side wall, for a distance equal to that between theintermediate leg and one of Y the supports 21, is a slot 30 throughwhich the end of the ear of corn is adapted to be forced by therotatable brush. In the other wall 29, there is formed a similarlongitudinal slot, between the intermediate leg and the support 21, forthe other end of the ear which is forced by the other'brush, Verticallyadjustable at each of these slots 30, is a plate 31, which regulates thesize of the opening, and consequently the amount of the end of the earwhich will protrude therethrough, as will be readily understood. I

Mounted on each of the side walls 29, near the purpose of producing-ashearingcut on! theesame having no bottom so that the ears ofrcorn willfall onto the'belt 19.: Inthe forwardfend: Wall of the: boxthere-isformedthe far end ofthe slot 30, are-brackets, 3 2, and supported ineach upper and lower bracket is the stepped shaft 34, of avbevel edgedcutting disk 33, eachpair, of disks being disposed in overlappingrelation for the heads and butts of the ears of the corn.
